-    TODO
- The following is a small list as to what is currently wrong/suggestions for
- ustdio.
-
- * Make sure that * in the scanf format specification works for all formats.
- * Each UFILE takes up at least 2KB.
-    Look into adding setvbuf() for configurable buffers.
- * This library does buffering. The OS should do this for us already. Check on
-    this, and remove it from this library, if this is the case. Double buffering
-    wastes a lot of time and space.
- * Test stdin and stdout with the u_f* functions
- * Testing should be done for reading and writing multi-byte encodings,
-    and make sure that a character that is contained across buffer boundries
-    works even for incomplete characters.
- * Make sure that the last character is flushed when the file/string is closed.
- * snprintf should follow the C99 standard for the return value, which is
-    return the number of characters (excluding the trailing '\0')
-    which would have been written to the destination string regardless
-    of available space. This is like pre-flighting.
- * Everything that uses %s should do what operator>> does for UnicodeString.
-    It should convert one byte at a time, and once a character is
-    converted then check to see if it's whitespace or in the scanset.
-    If it's whitespace or in the scanset, put all the bytes back (do nothing
-    for sprintf/sscanf).
- * If bad string data is encountered, make sure that the function fails
-    without memory leaks and the unconvertable characters are valid
-    substitution or are escaped characters.
- * u_fungetc() can't unget a character when it's at the beginning of the
-    internal conversion buffer. For example, read the buffer size # of
-    characters, and then ungetc to get the previous character that was
-    at the end of the last buffer.
- * u_fflush() and u_fclose should return an int32_t like C99 functions.
-    0 is returned if the operation was successful and EOF otherwise.
- * u_fsettransliterator does not support U_READ side of transliteration.
- * The format specifier should limit the size of a format or honor it in
-    order to prevent buffer overruns.  (e.g. %256.256d).
- * u_fread and u_fwrite don't exist. They're needed for reading and writing
-    data structures without any conversion.
- * u_file_read and u_file_write are used for writing strings. u_fgets and
-    u_fputs or u_fread and u_fwrite should be used to do this.
- * The width parameter for all scanf formats, including scanset, needs
-    better testing. This prevents buffer overflows.
- * Figure out what is suppose to happen when a codepage is changed midstream.
-    Maybe a flush or a rewind are good enough.
- * Make sure that a UFile opened with "rw" can be used after using
-    u_fflush with a u_frewind.
- * scanf(%i) should detect what type of number to use.
- * Add more testing of the alternate format, %#
- * Look at newline handling of fputs/puts
- * Think more about codeunit/codepoint error handling/support in %S,%s,%C,%c,%[]
- * Complete the file documentation with proper doxygen formatting.
-    See http://oss.software.ibm.com/pipermail/icu/2003-July/005647.html

- * \brief C API: Unicode stdio-like API
- *
- * <h2>Unicode stdio-like C API</h2>
- *
- * <p>This API provides an stdio-like API wrapper around ICU's other
- * formatting and parsing APIs. It is meant to ease the transition of adding
- * Unicode support to a preexisting applications using stdio. The following
- * is a small list of noticable differences between stdio and ICU I/O's
- * ustdio implementation.</p>
- *
- * <ul>
- * <li>Locale specific formatting and parsing is only done with file IO.</li>
- * <li>u_fstropen can be used to simulate file IO with strings.
- * This is similar to the iostream API, and it allows locale specific
- * formatting and parsing to be used.</li>
- * <li>This API provides uniform formatting and parsing behavior between
- * platforms (unlike the standard stdio implementations found on various
- * platforms).</li>
- * <li>This API is better suited for text data handling than binary data
- * handling when compared to the typical stdio implementation.</li>
- * <li>You can specify a Transliterator while using the file IO.</li>
- * <li>You can specify a file's codepage separately from the default
- * system codepage.</li>
- * </ul>
- *
- * <h2>Formatting and Parsing Specification</h2>
- *
- * General printf format:<br>
- * %[format modifier][width][.precision][type modifier][format]
- *
- * General scanf format:<br>
- * %[*][format modifier][width][type modifier][format]
